Title: Lead silicate glass insulation between coaxial electric leads - having lower thermal expansion then the leads to prevent fissuring
Inventor: MAYER PETER
IPC: C03C29/00
Filed: 1976-06-24
Abstract: Vacuum-tight glass insulation between an inner electric lead and an outer electric lead coaxially surrounding the inner lead is improved in that the glass has lower thermal expansion than both the electric leads. The coefft. of the thermal expansion of the latter (pref. both made of the same alloyed steel) is 180-220 x 10-7 degrees C-1; whilst that of the glass is 40-120 x 10-7 degrees C-1. The glass is based on lead silicate; the weight ratio PbO:SiO2 is 55:45 to 85:15. In addition the glass may contain (in wt. % w.r.t. PbO+SiO)2: GeO2 6-18, Bi2O3 0-8, BaO 1-9, CaO 0-2. MgO 0-2, ZnO 0-13, CeO2 2-3, Al2O3 0-5, ZrO2 0-2, Na2O 0-2, K2O 0-2. If the glass is used in a nuclear plant it should be free of B and Co. This glass is esp. suitable for use in nuclear installations, but it can also be employed in other applications involving extensive temp. fluctuations. The use of a glass having a lower thermal expansion than both the electric leads proved to be better than the conventional arrangement in which the expansion of glass was intermediate between the expansion of the two electric leads (the highest in the expansion of the outer lead), because there was no fissuring tendency. The electric resistance was very high.

Title: Typing field detector for processor controlled recorder - has optical sensor to detect frame-fixed marks and left hand paper edge
Inventor: BERTRAM RALF
IPC: B41J21/16
Filed: 1977-02-09
Abstract: A sensor is used to detect the typing field on a recording surface, usually a paper sheet to be type on as it moves in the line direction in a processor-controlled recorder. The sensor (6) comprises an optical reader e.g. a reflection unit, which detects the paper (5) and two frame-fixed marks (7, 8). On detecting one mark the sensor generates a signal to halt the typing mechanism in the left end position while on recognizing the other mark it produces a signal to decelerate the mechanism in its movement to the left. In the left end position of the typing mechanism a search routine controlled by the processor is activated by which the sensor detects the left edge (51) of the paper and generates a function signal by which all data are printed out in the correct position.

Title: Automatic digit and symbol indicator - has mechanical indicator elements with binary action to display individual characters
Inventor: WEINER LEONHARD
IPC: F02B3/06
Filed: 1977-02-19
Abstract: A mechanical indicator element with binary action (6) is driven by a drive element (8) and carrier (2) via a driving axle (9a) which crosses the bearing axle (9). The driving axle is suspended in points in the bearing pedestal free of friction. When the switching coil (4) or the resetting coil (5) are excited, they attract the plunger (7) and follow a mechanical path via the push rod (3) and carrier (2). This path results in an angle of rotation on the driving axle which gives the desired binary action to the mechanical indicator element. It is made as a tube and responds to the interplay between the resetting coil and switching coil.

Title: Underwater power cables - with conductive sheath of metal strip bonded to semiconductive layer by non-hardening adhesive
Inventor: HANSSON HANS OLOF
IPC: H01B7/282
Filed: 1977-07-15
Abstract: Underwater power cables have a structure consisting of (a) an inner solid or stranded conductor, (b) an inner semi-conducting layer, (c) a plastic insulating layer, (d) a conductive sheath in the form of lengthwise or spirally wound metal strip and (e) a plastic covering over the metal sheath. The conductive sheath is bonded to the semiconductive layer by a non-hardening adhesive which adheres well to the semiconductive layer and to the metal strip so that the conductive sheath forms a completely sealed covering round the core, the edges of the metal strip overlap one another and are bonded together by the adhesive, or a gap between the edges of the metal strip sheath is covered with a tape covered with the adhesive and which overlaps the edges. Pref. a layer of adhesive is placed between the sheath and the outer plastic layer of the same type as that between the sheath and the semi-conducting layer. Suitable adhesives are e.g. asphalt based materials or amixt. of 40-60 wt. % polyisobutylene with a mol. wt. of 10-12,000 and 60-40 wt. % of a high stability polyester resin. The construction of the cable prevents the ingress of water and overcomes corrosion problems previously encountered with metal sheathed cables, esp. when immersed in sea water.
